Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce GTX 965M
IntroThe GeForce 8600 GT 512MB DDR2 comes with a clock speed of 540 MHz and a DDR2 memory speed of 400 MHz. It also makes use of a 128-bit bus, and makes use of a 80 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 ROPs.Compare all that to the GeForce GTX 965M, which makes use of a 28 nm design. nVidia has clocked the core frequency at 944 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular model. It features 1024 SPUs along with 64 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 965M should in theory be quite a bit superior to the GeForce 8600 GT 512MB DDR2 in general. (explain)
Texel RateThe GeForce GTX 965M is quite a bit (about 599%) faster with regards to texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 965M is the winner, and very much so. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
